Generally, the lighter the shaft, the higher the ball flight. Graphite will almost always flight higher than steel. Were you fit for those shafts?

You can break down shafts as either not directionally stable or improper launch. The former is a better case for shaft allowing too much torque so the face closes too much, resulting in too much dispersion. Higher torque is good at slower speeds to help close the face and reduce fade. Launch is more of a shaft design. The Tensei Blue and Tensei White only vary by 2g on an R shaft, but the Blue is a higher launch shaft.

If you can find a fitter with an electronic launch monitor, it can tell you if for club head and ball speed if the launch angle is not ideal. At slower ball speeds, a higher launch is preferable compared to what a pro needs to optimize distance. Slower speeds also benefit from more spin to allow the ball to remain airborne longer and not dropping from the sky. TruFeel (higher launch) vs AVX (lower launch) or Pro-V1 (lower spin) will also impact flight if launching too high.

If life was still so simple to simply say steel versus graphite, but there is so much more crossover in function now.

I agree with Don O. In simple terms, if you're hitting"loose shots", meaning dispersion is not quite dialed in, you probably have too much torque in the shaft. A shaft with a low torque number should feel a little firmer at impact, and significantly improve shot dispersion.Graphite shafts as a rule have higher torque than steel shafts.

Also it may take a little time to adjust to graphite shafts.

I would recommend going to see a certified fitter. I am 74 and was asking my Titleist fitter if I should go to graphite in my irons and he said no, because the are a lot of newer steel shafts that are just a light and can give you a better feel. He has been with Titleist over 25 years and I trust him completely. I play T300s with a regular shaft. I try not to get technical on this site and just recommend seeing a fitter who is a pro and does it for a living. With respect.

I recently purchased the TSi Driver, 16.5 and 21 degree woods with the regular flex Tensei Blue Shafts. I had always hit stiff shafts in the past. So far I have only received the fairway woods due to back order on the Driver. However, after playing the clubs, I find that shot dispersion is horrible. I hit the ball and it feels good off the face and look up and the ball is peeling to the right.

Sadly, I used a Titleist Premier Club fitter and paid good money to be fitted and am walking away with a large spend on clubs that are much worse that the ones I was hitting. I called and changed the Mitsubishi Blue Driver to Stiff shaft, and hopefully will see straighter drives. The other clubs will either be sold or reshafted, but now have no confidence in the fitting process.

I have been around golf for 53 years. Both parents golf professionals, and my mom a head pro at a golf course where Bob Vokey was a club repairman in the back room at the time. I have always loved titleist clubs, but...
